A system and method for rendering high dynamic range images includes a rendering manager that divides an original luminance image into a plurality of original subband images. The rendering manager converts the original subband images into original contrast images which are converted into original perceived contrast images. The rendering manager performs a compression procedure upon the original perceived contrast images to produce compressed perceived contrast images. The rendering manager converts the compressed perceived contrast images into compressed contrast images which are converted into compressed subband images. The rendering manager performs a subband combination procedure for combining the compressed subband images together with a lowest-frequency subband image to generate a rendered luminance image. The rendering manager may combines the rendered luminance image with corresponding chrominance information to generate a rendered composite image.

Table data is stored by parsing the table data into columns of values, formatting each column into a data stream, and transferring each data stream to a storage device for storage as a continuous strip of data. The strip of data is stored as a file that is not structured as a series of pages. The formatting of the data stream may include compressing the column values to minimize the length of the data strip. A particular compression procedure may be used that derives a code for each value in the column from a number of occurrences of the value in the column and replaces the value in the data stream with the corresponding code.

A system and method for effectively encoding and decoding electronic information includes an encoding system with a tiling module that initially divides source image data into data tiles. A frame differencing module then outputs only altered data tiles to various processing modules that convert the altered data tiles into corresponding tile components. A quantizer performs a compression procedure upon the tile components to generate compressed data according to an adjustable quantization parameter. An adaptive entropy selector then selects one of a plurality of available entropy encoders to most effectively perform an entropy encoding procedure to thereby produce encoded data. The entropy encoder may also utilize a feedback loop to adjust the quantization parameter in light of current transmission bandwidth characteristics.

Embodiments of the present invention provide a compression capability for compressing a CRL, such as an X.509 CRL, stored as a file, data structure or data object in a computer system having a certification authority (CA) and a security client. An exemplary method provides for accessing the CRL contents including a certificate revocation record and performing compression procedure, such as a lossless compression procedure on the contents of the CRL. The compressed CRL contents can be stored in another file, data structure or data object. A request for the compressed CRL is from a security client whereupon the compressed CRL is returned to the security client by transferring the compressed CRL contents to the security client. The security can client un-compress the compressed CRL contents. In some cases the uncompressed CRL contents can be transferred to the security client. The compression procedure can further compress a body portion of the CRL and modify a header portion of the CRL to indicate that the body portion is compressed. The security client can read the header portion to determine that the CRL is compressed and can un-compresses the CRL.

A method and system for compressing motion image information, which can compress data that can be subjected to predictive encoding. An image within a frame is divided into blocks before an inter-frame compression procedure begins, and each block is approximated with a single plane represented by at least three components for pixels within each block. Pixels between the original image and the image expanded after compressed can be compared, and when a pixel that causes greater difference than a given parameter to occur exists, intra-frame compression is performed using a smaller block size. Furthermore, when the respective I blocks, which are spatially divided, are dispersed between each frame along the temporal axis, no I block is inserted into any block within the frame that has been updated due to difference between frames being greater than parameter P during a designated period of time.

Time-of-flight (TOF) clinical data collected during a PET scan are very sparse and have significant size. These data undergo TOF axial rebinning and azimuthal mashing if histogrammed data-based reconstruction algorithms are used. In a clinical environment, TOF compression is typically performed by the hardware rebinner. Normalization data, acquired on a regular basis and used for estimation of some norm components, are compressed by the hardware rebinner in a similar manner. This disclosure presents simple update iterative algorithms for crystal efficiencies norm component estimation from TOF compressed normalization data. Previously known methods are not directly applicable since the compression procedure significantly complicates normalization data model equations. The iterative algorithms presented herein have advantages of being easily adapted to any acquisition geometry, and of allowing estimation of parameters at crystal level when a number of crystals is relatively small. A monotonic sequential coordinate descent algorithm, which optimizes the Least Squares objective function, is presented. A simultaneous update algorithm, which possesses the advantage of easy parallelization, is also presented.
